When the malfunction indicator is
illuminated, the system may not be able
to detect or signal low tire pressure as
intended. TPMS malfunctions may occur
for a variety of reasons, including the
installation of replacement or alternate
tires or wheels on the vehicle that prevent
the TPMS from functioning properly.
Always check the TPMS malfunction
telltale after replacing one or more tires or
wheels on your vehicle to ensure that the
replacement or alternate tires and wheels
allow the TPMS to continue to function
properly.
The tire pressure monitoring system
complies with part 15 of the FCC rules and
with RSS-210 of Industry Canada.
Operation is subject to the following two
conditions: (1) This device may not cause
harmful interference, and (2) This device
must accept any interference received,
including interference that may cause
undesired operation.
Changing Tires With a Tire
Pressure Monitoring System
E142549
Note: Each road tire is equipped with a tire
pressure sensor located inside the wheel
and tire assembly cavity. The pressure
sensor is attached to the valve stem. The
pressure sensor is covered by the tire and is
not visible unless the tire is removed. Take
care when changing the tire to avoid
damaging the sensor.

You should always have your tires serviced
by an authorized dealer.
Check the tire pressure periodically (at
least monthly) using an accurate tire
gauge. See Inflating Your Tires in this
chapter.
Understanding the Tire Pressure
Monitoring System
The system measures the pressure in the
four road tires and sends the tire pressure
readings to your vehicle. The low tire
pressure warning light will illuminate if any
of the tire pressures are significantly low.
If the warning light is illuminated, one or
more of the tires are under-inflated and
need to be inflated to the correct pressure.
When the Temporary Spare Tire is
Installed
If one of the road wheels and tire needs to
be replaced with the temporary spare
wheel and tire, the system will continue to
identify a defect. This is to remind you that
the damaged road wheel and tire must be
repaired and refitted to your vehicle.
To restore the correct operation of the
system, you must have the repaired road
wheel and tire assembly refitted to your
vehicle. For additional information, see
Changing Tires with a Tire Pressure
Monitoring System in this section.
When You Believe the System is Not
Operating Correctly
The main function of the system is to warn
you when the tire pressures are low. It can
also warn you in the event the system is
no longer capable of operating correctly.
See the following chart for information
concerning the system:
